Description

Technical Field

[0001] The present invention relates to the field of waste lithium battery sorting devices, and in particular to a high-efficiency cascade sorting device based on waste lithium battery performance detection. Background Art

[0002] The waste lithium battery sorting device is a device used to recycle and process waste lithium batteries. Its purpose is to sort waste lithium batteries efficiently and accurately to facilitate subsequent resource recovery and reuse. The sorting of lithium batteries is not only environmentally friendly, but also can recycle precious metals and materials such as lithium, cobalt, nickel, etc. These materials are very important resources in the battery recycling process. However, during sorting, the feed rate of the mixed material of the diaphragm and other residual substances in the battery is difficult to control.

[0003] To address the above issues, a Chinese patent application provides a diaphragm separation device for recycling used lithium batteries (publication number: CN118990866B). When the mixed material is small, increasing the air inlet can increase the air volume, making it easier for the lighter diaphragm to be lifted and separated by the wind, avoiding incomplete separation due to insufficient wind power. When the mixed material is large, reducing the air inlet can increase the wind speed. Therefore, without increasing energy consumption, the higher wind speed can be used to achieve a good suspension and separation effect for the diaphragm. This ensures separation quality and avoids energy waste.

[0004] However, in actual use, the above technical solution has limitations in that it only controls the wind force at the air inlet by observing the amount of mixed materials. Even if the mixed materials are small, if they contain a large proportion of diaphragms, reducing the wind force will lead to insufficient separation. Similarly, even if the mixed materials are large, if they contain a small proportion of diaphragms, increasing the wind force will lead to energy waste. In addition, the separation process requires the operator to observe through the observation window and then adjust the equipment, which has a delay and easily affects the separation of the mixture. The degree of intelligence is low. Summary of the Invention

[0015] Preferably, the control panel is internally provided with a server, a fault analysis unit, an abnormality identification unit and a remote monitoring terminal;

[0016] The fault analysis unit is used to collect data from the operation process of the sorting device, set the total set and subset according to the collected data, and build a fault monitoring model. According to the analysis of the fault monitoring model, the fault risk trend of the sorting device is set to high abnormal risk trend and low abnormal risk trend. If the high abnormal risk trend is set, a sorting abnormality signal is generated synchronously and sent to the remote monitoring end via the server;

[0017] The abnormality analysis unit is used to perform risk analysis on the sorting device with a low abnormal risk trend, and infer whether there is an operational abnormality risk when the sorting device with a low abnormal risk trend is operated in conjunction with the analysis.

[0018] When the remote monitoring terminal receives a sorting abnormality signal, it issues a corresponding warning and immediately controls the partition plate to operate.

[0019] Preferably, the specific operation process of the fault analysis unit includes:

[0020] Collect the operating time of the sorting device and continuously monitor the operating time, and build the historical operating time based on the current monitoring time and the starting time of the operating time;

[0021] According to the historical operation period, the fault time of the sorting device is obtained, and the fault type at the fault time is set as a total set of the fault monitoring model, and multiple total sets are assigned serial numbers X1, X2, X3...Xn.

[0022] According to the causes of the total set corresponding to the fault types, the cause types are counted and marked as subsets, and multiple subsets are assigned serial numbers Y1, Y2, Y3...Yn.

During the coordinated operation of the cooperative monitoring equipment, collect data on the basic events corresponding to the marked subsets in the cooperative monitoring equipment, and process the basic event data to obtain corresponding deviation values.

[0031] If the deviation value exceeds the set threshold, it is inferred that the current basic event affects the operating status of the cooperative monitoring equipment, and the current collected data type is sent to the remote monitoring end, which continuously monitors the cooperative monitoring equipment.

[0032] The beneficial effects of the present invention are as follows:

[0033] (1) The present invention uses a combination of transverse tube 1, transverse tube 2 and separation tube to transport the crushed waste lithium battery mixture from the feed hopper to transverse tube 1. At this time, the fan 1 is started to drive the mixture toward the separation tube under the action of wind. During this process, the airbag is expanded and the magnetic block is magnetized. The airbag is used to control the internal diameter of the pipe. At the same time, the tilted airbag is used to form a three-dimensional vortex effect on the airflow carrying the mixture. At this time, under the action of the gradient magnetic field, high-resistance impurities are gradually lifted to the upper layer under the action of centrifugal force, and low-resistance impurities offset part of the centrifugal force through the magnetic field force. Therefore, the low-resistance impurities gradually gather in the lower layer, thereby achieving preliminary stratification of impurities.

[0034] When the airflow passes through the convergent tube and enters the second horizontal tube, the airflow velocity increases due to the narrow tube effect, further improving the sorting and stratification effect. When the airflow reaches the divergent tube, the flow velocity gradually decreases, and the stratified impurities are separated by the moving guide plate. At this time, low-resistance impurities enter the upper part of the fixed guide plate, and high-resistance impurities enter the lower part of the fixed guide plate, thereby realizing the sorting of the mixture.

[0035] (2) The present invention also extracts and identifies features during the operation of the sorting device to accurately evaluate the impact of the collected data. By combining the impact of the collected data itself and its impact on the sorting device, the control of the sorting device is improved. When a fault occurs, the fault can be quickly traced according to the fault monitoring model. The corresponding structure can also be controlled to perform compensatory operations based on the evaluation results, thereby fundamentally reducing the impact of the fault and improving the operating efficiency of the sorting device.

[0036] At the same time, the sorting devices with low abnormal risk trends are analyzed to infer whether the power equipment with low abnormal risk trends currently have the risk of high abnormal risk trends when operating in coordination with each other, thereby effectively improving the accuracy of status monitoring of the sorting devices.

[0048] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] Embodiment 1: This embodiment is used to solve the problem that controlling the wind force at the air inlet by simply observing the amount of mixed materials has limitations and easily leads to energy waste.

[0050] See also Figure 1 - Figure 6As shown, this embodiment is an efficient cascade sorting device based on performance testing of waste lithium batteries, including a fixed tube 1, which is composed of a transverse tube 11, a tapered tube 12, a transverse tube 2 13, a gradually expanding tube 14 and a separation tube 15 fixedly connected in sequence, a feed hopper 16 is fixedly installed on the top of the transverse tube 11, a fan 17 is fixedly installed on the end of the transverse tube 11 away from the tapered tube 12, and a sorting component 2 is fixedly installed inside the fixed tube 1.

[0051] The sorting component 2 includes an airbag 21 and a magnetic block 22, which are fixedly installed on the inner walls of the transverse tube 1 11, the convergent tube 12, the transverse tube 2 13 and the divergent tube 14. The magnetic block 22 is an electromagnet, and the magnetism of the magnetic block 22 is controlled by the amount of current.

[0052] The airbags 21 are arranged at an angle, wherein the total length of the fixed tube 1 is 5m, the diameter of the transverse tube 11 is 300mm, the maximum diameter of the convergent tube 12 and the divergent tube 14 is 300mm, and the minimum diameter is 120mm, the diameter of the transverse tube 2 13 is 120mm, and the length of the transverse tube 2 13 is 2m. Multiple airbags 21 are arranged in the transverse tube 11, the convergent tube 12, the transverse tube 2 13 and the divergent tube 14, and the multiple airbags 21 are evenly spaced on the inner wall. When the fan 17 is started, the airflow carries the mixture into the convergent tube 12 at a speed of 12m / s. At this time, the difference in the suspended height of the debris reaches 50-80mm. Under the action of multiple inclined airbags 21, the airflow is induced to form a vortex.

[0053] When the airflow enters transverse tube 2 13 from transverse tube 11, the channel inlet diameter is 300 mm, and the tapered tube 12 narrows at a 15° angle to a throat diameter of 120 mm. The airflow velocity increases from 12 m / s at the inlet to 25 m / s at the throat, forming a low-pressure area in transverse tube 2 13. When the battery fragments enter the low-pressure area, the pressure difference between the upper and lower surfaces generates lift.

[0054] That is, first, a crushing device is used to crush the waste lithium batteries. After crushing, the mixture is transported from the feed hopper 16 to the horizontal pipe 11. At this time, the fan 17 is started, and the mixture is driven to move toward the separation pipe 15 under the action of wind. During this process, the airbag 21 is expanded and the magnetic block 22 is magnetized. Multiple magnetic blocks 22 are fixedly installed on the inner wall of the fixed tube 1, and are evenly spaced on the inner wall of the fixed tube 1. The electromagnetic blocks are energized to generate magnetism and their installation methods are both existing mature technologies, which will not be described in detail here.

[0055] The airbag 21 is used to control the internal diameter of the pipe. At the same time, the inclined airbag 21 is used to form a three-dimensional vortex effect in the airflow containing the mixture. At this time, under the action of the gradient magnetic field, high-resistance impurities are gradually lifted to the upper layer due to the centrifugal force. The low-resistance impurities are partially offset by the centrifugal force through the magnetic field force, so the low-resistance impurities gradually gather in the lower layer, thereby achieving preliminary stratification of impurities.

[0056] When the airflow passes through the convergent tube 12 and enters the second horizontal tube 13, the airflow velocity increases due to the narrow tube effect, further improving the sorting and stratification effect. When the airflow reaches the divergent tube 14, the flow velocity gradually decreases, and the stratified impurities are separated by the movable guide plate 24. At this time, low-resistance impurities enter the upper part of the fixed guide plate 25, and high-resistance impurities enter the lower part of the fixed guide plate 25, thereby realizing the sorting of the mixture.

[0057] Embodiment 2: This embodiment is used to solve the problem that during the separation process, the operator needs to observe through the observation window and then adjust the equipment, which has a delay, easily affects the separation of the mixture, and has a low level of intelligence.

[0058] See also Figure 6 - Figure 8 As shown, the present invention further includes a control panel 3, which is fixedly mounted on one side of the fixed pipe 1. The control panel 3 is internally provided with a server, a fault analysis unit, an abnormality identification unit and a remote monitoring terminal;

[0059] The fault analysis unit is used to collect data from the operation process of the sorting device, set the total set and subset according to the collected data, and build a fault monitoring model. According to the analysis of the fault monitoring model, the fault risk trend of the sorting device is set to high abnormal risk trend and low abnormal risk trend. If the high abnormal risk trend is set, a sorting abnormality signal is generated synchronously and sent to the remote monitoring end via the server;

[0060] The abnormality analysis unit is used to perform risk analysis on the sorting device with a low abnormal risk trend, and infer whether there is an operational abnormality risk when the sorting device with a low abnormal risk trend is operated in conjunction with the analysis.

[0061] The specific operation process of the fault analysis unit includes:

[0062] Collect the operating time of the sorting device and continuously monitor the operating time, and build the historical operating time based on the current monitoring time and the starting time of the operating time;

[0063] According to the historical operating period, the fault time of the sorting device is obtained, and the fault type at the fault time is set as the total set of the fault monitoring model, and multiple total sets are assigned serial numbers X1, X2, X3...Xn. It should be noted that since the fault time generated by each sorting device in the historical operating period is different, the type and number of total sets generated by each sorting device in the fault monitoring model are different. For example, sorting device 1 has total sets X1, X3 and X4 in the historical operating period, and sorting device 2 has total sets X2, X3, X4 and X6 in the historical operating period.

[0064] At the same time, based on the causes of the total set corresponding to the fault type, the cause types are counted and marked as subsets. Multiple subsets are assigned serial numbers Y1, Y2, Y3, ... Yn. It should be noted that the total set is also a subset because a sorting device fault will affect other cooperating equipment. However, this scenario is the status monitoring of the sorting device, so it is calibrated as the total set, specifically for fault types such as fan failure.

[0065] According to the causes of the total set corresponding to the fault type, the cause types are counted through the collected data of the historical operation period and marked as subsets, such as the fan running but not sorted or the fan not running;

[0066] According to the correlation analysis of the subsets, a relationship is established between the total set and the subsets, specifically a causal relationship, that is, the total set X1, X2, X3...Xn is in one-to-one correspondence with Y1, Y2, Y3...Yn;

[0067] The currently constructed subset Yn is set in the same layer of grid of the fault monitoring model, and the next layer of grid is constructed, that is, the basic event Zn is collected for the current subset, and the serial numbers Z11, Z12, Z13...Zni are assigned according to the type of basic event, where n and i are positive integers, where n represents the correspondence between basic events, subsets and total sets, and i represents the type of basic event. For example, the total set X1 corresponds to the subset Y1, and the basic events corresponding to the subset Y1 are Z11, Z12, and Z14. The total set X3 corresponds to the subset Y3, and the basic events corresponding to the subset Y3 are Z32, Z35, and Z36. Z12 and Z32 represent basic events of the same type corresponding to different subsets.

[0068] Each grid layer of the fault monitoring model is continuously updated at each moment in the historical operation period, and the number of basic event types and the rate of increase are collected during the updating process.

[0069] If the sum of the increased quantities is greater than a preset quantity threshold or the quantity increase speed is greater than a preset speed threshold, the current sorting device is marked as having a high abnormal risk trend.

[0070] If the sorting device is set to a high abnormal risk trend, a sorting abnormality signal is generated synchronously and sent to the remote monitoring end via the server. When the remote monitoring end receives the sorting abnormality signal, it issues a corresponding warning and immediately controls the partition plate 26 to work.

[0071] Among them, the sorting component 2 also includes a fixed frame 23, a movable guide plate 24, a fixed guide plate 25 and a partition plate 26. The fixed frame 23 is fixedly installed in the separation tube 15, the movable guide plate 24 is movably installed in the fixed frame 23, the fixed guide plate 25 is fixedly installed in the separation tube 15, and the partition plate 26 is movably installed below the separation tube 15. A through groove 27 is opened at the bottom of the separation tube 15, and a sealing member is provided in the through groove 27 for sealing the separation tube 15. A temporary storage tank 28 is fixedly installed on one side of the separation tube 15, and a fan 29 is fixedly installed on the side of the separation tube 15 away from the temporary storage tank 28.

[0072] The separation tube 15 is divided into an upper cavity and a lower cavity by a fixed guide plate 25. A discharge pipe 30 is fixedly installed at one end of the upper cavity and the lower cavity. An electric push rod is fixedly installed at the bottom of the separation tube 15. Two partition plates 26 are provided. The bottoms of the two partition plates 26 are fixedly connected by a connecting plate, and the connecting plate is fixedly connected to the output end of the electric push rod.

[0073] Rotating rods are fixedly installed on both sides of the movable guide plate 24. One end of the rotating rod passes through the fixed frame 23 and the separation tube 15. A motor is fixedly installed on one side of the separation tube 15. The output end of the motor is fixedly connected to the rotating rod. The rotating rod is driven to rotate by the motor, and then the inclination angle of the movable guide plate 24 is controlled. That is, by changing the inclination angle, the height of the fragment layer is adjusted to adapt to a variety of sorting scenarios.

[0074] The working principles of the partition plate 26 and the movable guide plate 24 are as follows:

[0075] The multispectral sensor is used to detect the debris in the separation tube 15 below the fixed guide plate 25. If the detection membrane residue is greater than 2%, the electric push rod is activated, driving the connecting plate to move up, thereby driving the two partition plates 26 to move up, so that the partition plates 26 move from the through groove 27 to the separation tube 15 until the partition plates 26 touch the bottom of the fixed guide plate 25. The two partition plates 26 are used to isolate the lower layer of the separation tube 15. At this time, the temporary storage tank 28 on one side of the separation tube 15 is opened, and the second fan 29 is started. The airflow is used to blow the debris in the isolation area into the temporary storage tank 28, so as to collect the abnormal debris and prevent it from mixing with the separated fragments and affecting the overall sorting.

[0076] Collecting the total set data of the sorting device with a high abnormal risk trend and the corresponding subset data of the total set, analyzing the subset data, and then obtaining the basic event data corresponding to the subset, and marking the basic event data as a risk event;

[0077] All subsets in the fault monitoring model and their corresponding basic event types are collected and compared, the subset Yn corresponding to the basic event type Zni containing risk events is marked, and the sorting device containing the marked subset is marked as a low abnormal risk trend.

[0078] It should be noted that each subset Yn may correspond to multiple basic event types Zni, such as Figure 9 As shown, when the sorting device 1 has a total set X1 in the historical operation period, the total set X1 corresponds to a subset Y1, and the basic event types corresponding to the subset Y1 are Z11, Z13, Z15 and Z16;

[0079] When the total set X2 appears in the historical operation period of the sorting device 2, the total set X2 corresponds to the subset Y2, and the basic event types corresponding to the subset Y2 are Z22, Z24, Z26 and Z27;

[0080] At this time, if sorting device 1 is set to a high abnormal risk trend, and the abnormal basic event belongs to subset Y1, Z11, Z13, Z15 and Z16 are all marked as risk events. Although sorting device 2 has no abnormality at this time, sorting device 2 contains the total set X2, and its corresponding subset Y2 contains the risk event Z26. At this time, risk device 2 is marked as a low abnormal risk trend.

[0081] The specific operation process of the abnormal analysis unit includes:

[0082] Mark the sorting devices with low abnormal risk trends as cooperative monitoring equipment. During the coordinated operation of the cooperative monitoring equipment, collect data on the basic events corresponding to the marked subsets in the cooperative monitoring equipment, and process the basic event data to obtain corresponding deviation values.

[0083] The specific method for obtaining the corresponding deviation value is as follows:

[0084] The operating data of the cooperative monitoring equipment is collected, that is, all basic event data contained in the subset to which the risk event belongs are collected. For example, when the risk events are Z11, Z13, Z15 and Z16, the subset Y2 of the sorting device 2 contains the risk event Z26. At this time, the data of all basic event types Z22, Z24, Z26 and Z27 in the subset Y2 are collected.

[0085] A coordinate system is constructed with time as the X-axis and the basic event data collection value as the Y-axis. The basic event data curve is drawn in the coordinate system, and the threshold value set for the corresponding data type is drawn in the coordinate system. If the basic event data fluctuates, it will float up or down on the coordinate system, that is, the area of the floating waveform deviation region between the basic event data curve and the threshold curve is calculated, and the area of the floating waveform deviation region per unit time is the deviation value.

[0086] If the deviation value exceeds the set threshold, it is inferred that the current basic event will affect the operating status of the coordinated monitoring equipment. That is, the currently collected basic event data type is sent to the remote monitoring end, and the remote monitoring end continuously monitors the corresponding sorting device, effectively improving the control efficiency and minimizing the failure rate of the sorting device.

[0087] It should be noted that the set thresholds are all threshold values manually set by the personnel in the field of sorting device operation based on historical operation failure scenarios. If the set threshold is not suitable for the current scenario, the threshold is updated to ensure accurate data detection in the current scenario.

[0088] Combining Example 1 and Example 2, it can be seen that it is possible to collect data inside the sorting device, build a fault monitoring model, and conduct comprehensive and efficient supervision during use, that is, to comprehensively analyze and compare the collected data range with the preset data range, thereby obtaining relevant evaluation signals, and accordingly issuing corresponding warnings to the remote monitoring end, thereby achieving accurate judgment and control of the sorting device, and for sorting anomalies, through the cooperation of the partition plate 26 and the movable guide plate 24, the abnormal sorting fragments are collected and the layered collection height is adjusted, thereby effectively improving the sorting effect of the fragments.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the contents of this specification.
